This rare word, probably borrowed from another language, refers to an expensive and elaborate garment. It appears in Isaiah's catalog of feminine finery that will be stripped away in judgment. The ancient versions struggled with it—the Septuagint offered "purple tunic," the Vulgate "breast-band." The uncertainty reflects the word's foreignness and rarity, but the context makes clear it's a luxury item, a symbol of the vanity and excess that Isaiah condemns.
